Outline 2 common sources of radiation in laboratory
1. Radioactive isotopes: Many laboratories work with radioactive materials as part of their research or medical applications. These materials emit radiation as they decay, which can be in the form of alpha, beta, or gamma radiation. Common radioactive isotopes used in laboratories include iodine-131, carbon-14, and tritium.
2. X-ray machines: X-ray machines are commonly used in laboratories to visualize the internal structures of objects and biological samples. These machines emit high-energy photons, known as X-rays, which penetrate materials and create an image on a detector. X-ray machines can produce both ionizing and non-ionizing radiation depending on the energy level used. While X-rays are generally safe in controlled settings, prolonged or excessive exposure can pose health risks.
